Built for flash-storm protection, the 100% waterproof, super-breathable Helium II weighs an incredibly light 5.5 ounces. An ultra-compressible piece you’ll never leave behind, it’s so light and packs down so small you’ll forget it’s clipped to your harness until you throw it on to ward off a sudden mid-route downpour.

RATING AND REVIEWS

Best Ultralight Rainjacket for Everything

5

Perfect for trail running - it's nearly as light as the Patagonia Houdini, but has the benefit of actually being waterproof. It's my go-to jacket for backpacking and fastpacking/ultras because of how insanely light and packable it is.
I also always keep it my pack while bike commuting around soggy/steamy Atlanta. Even in pouring rain while riding a bike it has kept my top bone-dry and it breathes great.
Basically the only thing I don't use it for is mountaineering, where I use a thicker, more durable shell.
I'm 5'7" and 145lbs. The medium fits perfectly, although potentially a bit short on my longer-than-average torso. But that's negligible.
Highly recommend this one!

The creme de le creme of ultralight backpacking jackets

5

This jacket is everything I have ever wanted in a UL jacket. Under 5.5 ounces (for an XS), waterproof, packs incredibly small, and cute enough to wear off-trail, too. As a petite lady, I often struggle to find outdoor gear that fits my short arms and legs but this jacket was spot on in fit. The sleeves end exactly where I need them too and the torso is not overly bulky. Props to OR for making such a solid piece of gear! I anticipate hanging on to this jacket for a long, long time.
The biggest downside, in my opinion, is the lack of pockets. I'll deal with it for the weight savings, but I've found myself trying to stuff my hands into invisible pockets on more than one occasion...

Perfect Light Weight Rain Jacket

5

I was looking for a lightweight, waterproof jacket that I could add layers under. This little rain coat was perfect for my 9 day hiking trip - it fit all of my criteria and kept me dry during 1 day of rain. It is a keeper!

Zipper failed

4

This jacket held up pretty well to the rain until day 3 of use when the zipper split open. Then it wouldnt zip and it was a major bummer trying to stay dry hiking in the rain with the jacket hanging open. If the zipper worked better, I'd give this 5 stars!

Light-as-air rain jacket

4

Really like this jacket. Extremely light and packable. Comfortable for hikes, bicycling, skiing, and just being outside. Love the extra extended built-in visor on the hood and front pocket for easy retrieval of items. Would have given it five stars, but...it really needs more pockets and the arm cuffs are not adjustable to prevent rain from entering the sleeves while biking. All in all, though, this rain jacket is by far the best jacket I've owned for a very fair price. The womens' Ultraviolet color is beautiful too. Thanks, OR!

works great in the Olympic rain forest

5

The Helium was rec'd by a friend for aerobic pursuits in not ideal weather. I have worn it only once so far, on a 56 day backpack in the Olympics, with the last 2 days of persistent rain forest showers and wet shrubbery. It worked fabulously. I was never too warm or too cold or too wet.

Sweet Jacket!

Super lightweight and breathable rain jacket perfect to take on backcountry days when you want to keep weight/space to a minimum. Super impressed with how waterproof it is...kept me bone dry during several very wet hikes.
